Looks like a simple issue with cables, but I'm not sure - need help

It's a somewhat long story, but please bear with me:

A couple days ago I received a new WD hdd, installed it on my computer and even had people here help me with a strange issue I had during the process. Let me quote myself on a post from a few days ago: I was installing my new hdd, and the OS didn't seem to recognize it. While trying to fix that, the computer failed to boot for the first time, then...

Quote:
I slowly started laying the case down to peer inside the working machine (the side lid was open) and it suddenly started booting. After some investigation, here's what I found out: When I tilted the case to the side, it booted normally. When in the usual upright position, it didn't. When the case was upright, my primary hdd was dead. Case laying horizontally, it came back to life.


Well, a short time after that, I've managed to install everything and have two working hard drives. Well, flash forward a couple of days, my computer failed to boot again after I decided to clean the CPU fan. But this time the position of the case didn't matter, it simply wouldn't boot. After messing with cables and plugs for two hours trying to understand what happened, I did something right and it came back. And then it failed to boot AGAIN yesterday. Pissed and committed to the problem, I spent an hour troubleshooting, until I mistakenly connected the secondary hdd to the primary hdd's red cable, at which pointed I noticed... there was no noise. See, it makes a little noise (like a faint whistle) when power is turned on, and now it didn't. So I proceeded to connect the primary drive to the other cable, and it worked. Really, it was only a cable? I then borrowed the cable from my optical drive and I soon had both hdds working.

The only reason I am here asking your opinion is because at some point when I was trying to reboot, a message came on the screen saying something about hard drive issues. I am still baffled by all this and my knowledge of hardware is limited. Do you guys think any harm was done to my primary hard drive? Do these SATA red cables often fail like this? What should I do if it happens again?

Thanks a lot for reading guys

  1. A sata hard drive needs both a sata power connector and a sata data cable.
    You need both to have a functioning hard drive.
    Some sata data cables will have a clip on it to keep the cable from dislodging.
    I think you may have had a loose connection.
    If your psu is modular, check the power cable to the psu.

    I doubt that any damage was ever done to either drive.
    It is possible that one of the drives has a poor attachment to either the data or power connector.

    If you find that to be the case, rma the drive.

    Yes, both power and data cables were on on the primary hard drive. I guess either the data cable was defective or the problem is on the hd itself. Yesterday I bought a new psu, because the old one was noisy and weak, tested it and still had the same problem. So I could rule out psu or mobo issues, since when I disconnected everything the BIOS came on. Only when I changed the cable things came back to normal.

    Sata cables are cheap. It might pay to test our some different cables.
    In theory, speed is not an issue, the specs for cables are the same. But modern sata III is faster so better quality cables would not be expensive to implement.
